Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, or 1000BASE-LX) can be used for a backbone connection between switches, or for connecting to a high-speed server.

Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.

Caution: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

1.Remove and keep the LC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2.Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3.Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Figure 4-3. Making LC Port Connections

4.As a connection is made, check the green Link LED on the switch corresponding to the port to be sure that the connection is valid.

The 1000BASE-SX and 1000BASE-LX fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet Collision Domain” on page 4-4.
